  2. Colony Management is divided into four steps Attract Colonist, Gather Resources, Provide Energy and Guard the colony. Setup tents to attract workers, set up mills, cottages to gather food, construct Tesla Towers and Mills for power and build walls, gates, to protect the colony.
  3. To save time follow this build order, Cottages for food, around 6 to 7 tents, Sawmill, Wood Workshop, another Sawmill, Farms and then Marketplace.
  4. At some point, you will not be able to expand more, focus on upgrading existing buildings.
  5. Wood and Stone Towers are best to prevent Runners, they are good for defending your colony from inside. Zombies will attack whatever comes in their path so if you spot a horde then place a piece of wall. They get engaged for a while, till the time plan out your strategy.
  6. Always clear the surrounding zombies who are rotating around the camp. Clear them up to avoid unnecessarily wasting soldiers on them.
  7. Seal your colony before the first attack, that is around Day 20. Before it is not really necessary to create a good defense, save your resources. After Day 20 zombies will swarm from all direction.
  8. Try expanding your colony before the first wave of attack and get as much land as possible to increase your gold revenue.
  9. Aim to get around 2000 or higher colonist before the first attack, and keep on increasing the number till you reach the final day.
  10. Standard soldiers, rangers, snipers will reach veteran-status after killing enough zombies. They will level up and double their attack speed.
  11. Support your Towers, with turrets or snipers, that will help you to protect the towers from spitters and harpies.
  12. Attack Villages of Doom when you have enough soldiers like around 30 snipers, you will earn a lot of resources from there.
  13. There is one trick to minimize casualties if you are attacked by a zombie horde, set a group of soldiers in one place and control only one to walk around the zombies. That one soldier will attract them to follow keep running around near your group so that they can take them down and you don’t lose much of your soldiers. This is called kiting.
